I IMPROVEMENT IN FLUTlNG-MACHINES.

Specification forming part of Letters Patent No. 213,724, dated March25, 1879; application filed September 11, 1878.

To all whom it may concern:

Be it known that I, JAMES E. WILSON, of Bridgeport, county of Fairfield,and State of Connecticut, have invented new and useful Improvements inFluting-Machines, which improvements are fully set forth in the annexed.specification and accompanying drawings.

My invention belongs to that class of flutin g-machines whereby thefluting is produced by rolling the material to be fluted between heatedfluted rollers.

The object of my invention is to so simplify the construction of suchmachines as to materially reduce their cost and make them more compactand easier to manipulate.

Referring to the drawings, which consist of two sheets and threefigures, Figure-1 is a side elevation of my fluting-machine with therollers closed together. Fig. 2 is likewise a side elevation with therollers set apart. Fig. 3, Sheet 2, is an end elevation of the machine;and Figs. 4 and 5, modifications.

Like letters refer to like parts in the difierent figures.

A is the frame of the machine. B is the lower roller-support. C is aspring-arm on support B. D is a spiral spring. h is a stud for thespring on frame A. d d are trunnionpins on which roller-support Bswings. E is a cam-shaft, operated by a handle, I). a a are hearings onframe A for cam-shaft E. w w are trunnion-pin bearings on frame A. H isa clamp-jaw in frame A. I, is a clamp-screw. K is the upper hollowroller. L is the lower roller. 6 e are pins holding cam-shaft E down inits bearings. 43 is a pin steadying roller K in its bearings. n is acrank, pinned or otherwise attached to the end of roller L. J is aroller-arm, supporting the outward end of roller K.

Fluting-machines, as heretofore generally constructed, have been madewith both rollers hollow for the reception of heating-irons, and themovable roller placed on the top; but I find that one heated rollerserves the purpose quite as effectually as two, and so made they costless.

By my arrangement of hanging the lower roller-support by one end inframe A, and operating it by cam-lever E and spring "D to open and shutthe rollers, I obviate the expense of a large flat-based frame, such.asis usually made, and the employment of a pivoted top-roller holder andcompressing-spring and thumb-screw.

Fluted rollers with a greater or less number of flutes can be usedinterchangeably in my machine as in others.

The operation of my machine is as follows: Having been properly fastenedto a table or bench, as above mentioned, and a heating-iron inserted inhollow roller K, handle 11 is swung over,as shown in Fig. 2. Thisoperates to crowd the cam-shaft E against the inner side of spring-arm Oon lower roller-support, B, and, swinging on trunnion-pins b b inbearings w as, said roller-support and roller L are thrown thereby intothe position shown in said Fig. 2. As cam-shaft E swings over, pin 8(shown in dotted lines on arm C, Fig. 3) comes up against the lower sideof roller-sup port B, and prevents the shaft from being turned farenough to derange spring D.

With roller L in the position just described the material to be flutedmay be easily in serted between the rollers, and by bringing handle bback to a vertical position the rollers are brought closely in contactagainst it, and held so by the tension of spring D upon arm C.

Crank 1:. may now be turned, and, both rollers moving together with thematerial be tween them, the latter is thereby properly fluted, and maybe run entirely through and beyond the rollers; or they may be againopened by touching handle I), and the mate rial be removed from betweenthem.

The operation of opening and closing the rollers by operating them witha cam and spring and the handle bis found to be very much moreconveniently and rapidly accorm plished than by any means heretoforeadopted.

This mode of so operating those parts is made practical and easy byhaving the movable roller L operate in a roller-support, B, whichsupport is pivoted on trunnion-pins d d at one end of the second roller,K.

There might be a modified construction of said roller-support andcam-shaft, as in Fig. 4, whereby the lower or movable roller could beoperated to open from and close against the other roller in the frame,as and for the purpose before described, by prolonging the trunnion. d,and providing it with a handle whereby the trunnion and frame could beadjusted. Thus modified, the cam-shaft might be dispensed with.

The said second modification, Fig. 5, may be as follows, viz: Thecam-shaft and handle may be omitted entirely, and the lowerrollersupport, B, made and hung to the pin d, as shown, with theaddition or not of a convenient finger-rest, 10, on the outer end ofsaid support, whereby that end may be pressed down against theresistance of spring D, for the purpose specified.

Instead of obtaining the continuous forcible contact of the two rollersby the employment of spring-arm G and spring 1), any other suitablespring may be applied to bear up directly against the under side ofroller-support B, as in dotted lines Fig. 5, the support being pivotedat d.

If constructed substantially according to either of the modifications Ihave described, my machines would not be so convenient to manipulate, asthe operator would have to hold the rollers apart while inserting thework between them, while the camshaft once turned against spring-arm 0keeps the rollers apart at the pleasure of the operator.

Of course some operative device for keeping the rollers open might beadded if the camshaft were left ofi; but I prefer to construct themachine as shown, as it thus combines the most convenient andpractically-operating devices for the purpose set forth.

What I claim as my invention is 1. In a fluting-machine, the frame A,having an arm, J, carrying the roller K and provided with the clamp H,and the arm B, pivoted at one end to the frame A, carrying the roller L,and the spring D, arranged to elevate the pivoted frame of the roller L,substantially as set forth.

2. Frame A and roller K, in combination with roller-support B, pivotednear one end and lower roller, L, spring-arm 0, spring D, and cam-shaftE, arranged to operate on the arm U, substantially as and for thepurpose set forth.
